The new hero might actually be insanely strong, if as a kid he was chopping trees with a practice sword. I wonder who will snap him out of his trauma caused cowardice?
Notice how both heroes have distinct protagonist hair. I wonder if there is more to how and who is chosen as each generation's hero too. Maybe they are all distantly related to the time mage/first hero?
Also, I bet the real reason he didn't pick Albus again was, because he was just about to slip into non-existence too.
